Ap. Levich et al., RATIONAL FERTILIZATION OF FISH PONDS POPU LATED BY DIFFERENT SPECIES, Izvestia Akademii nauk SSSR. Seria biologiceskaa, (1), 1996, pp. 121-124
A modified system of fertilization of fish ponds is described, which t
akes into account the requirements of plant-eating fish in food phytop
lankton and the requirements of the latter in components of mineral fe
eding. Biological substantiation of the new system is provided and the
results of its testing in fish ponds are presented. The results obtai
ned suggest an increase in fish productivity, as compared with the con
trol, and shifts in taxonomic and size structure of the phytoplanktoni
c community.
